.To all whom it may concern.-

Be it known that I, CHARLES L. MARBURG, of the city of Baltimore and State of Maryland, have made certain new and usefullmprovements in Machines for Preparing and Caslng Tobacco, of which the following is a full description.

Figure l is a front side view of the apparatus; Fig. 2, a sectional View of the same; Flg. 3, a view of the receiving box when let down. Fig. 4 is an end view of the apparatus showlng the receiving box and table in section, and the end of the revolving cylinder; Flg. 5, an end View of the apparatus showing tank, holding the casing material with ythe end doors closed; Fig. 6, an end view of the same Withthe doors opened and showing the interior of the revolving cylinder with the de-v vices for agitating the tobacco While the cas- 1ng 1s applied; Fig. 7,aview of the tank from which the casing matter is takenand from which it is discharged into its final tank tol be sprayed upon the tobacco.

Viewing Fig. 1,Ais a cylinder provided interiorly with screw flanges, as shown in Fig. 2, and enlarged at its end A into the shape of a funnel. B, a table upon which the tobacco is rst placed when taken from the receiving box C which then passes through the opening a in the cylinder. Suitable means for revolving this cylinder is shown in Fig. 1,

in which D is a shaft revolved by appropriate machinery for the purpose, and provided with a pulley d fitting into a groove d2 in a wheel d3 which surrounds the cylinder. A suitable bearing as d4 may be located at the bottom in order to give an even and regular movement to the revolution of the cylinder. Any other suitable device for operating the cylinder may be employed.

The funnel-shaped end of cylinderA is provided With pins or pegs a2 Whose office is to 'lift and support the tobacco While it is sprinkled with the casing material. At the other end of the apparatus is a steam pipe E entering through the aperture a. of the cylinder. This steam pipe is connected with a source of steam supply and is provided with apertures e2, through Which the steam escapes and steams the tobacco as it passes. A movable tank F contains the casing compound. This tank is provided with couplings ff2 to\ which are connected the pipes fk-f These pipes are provided with the cocks fs-f. An air-pressure pipe H, connected With a compressed air supply, extends to the casing receptacle I and is provided with the cock h. The tank I, which contains the liquid casing, is .provided with the pipe 't2 having acock i3. The other end of this pipe is provided with a spraying device 4. This spraying device is so located that it will throvvr the sprayed casing upon the tobacco as it is lifted and agitatedl by the pegs a2. The receiving box C is hinged as shown at c and connected with this box are one or more straps or cords c2 which are Wound upon a suitable reel or reels c3 secured to the shaft c4. A Worm as c5 operates a cogvwheel c6 and revolves the shaft c4.

' The mixture or material which is employed in flavoring and giving consistency or color to v the tobacco is called in the trade the casing. The operation of the device is as follows:

The tank F having been supplied with casing .the tank F as shown in dottedlines in Fig.1.

The cocksf--f6 are opened and the cock h is closed. Compressed air is then admitted through the tube H, into the tank F, through the pipe f3, exerts itsY pressure upon the top of the liquid casing in the tank, and forces it out through vthe pipe f4 and cock f6 into the tank I.A The cocks f5 and f6 are then closed and the tank F is removed if desired as the casing material has passed therefrom into the tank I, and the compressed air passes direct through cock h to exert its .pressure upon the casing in that tank. The tobacco `is placed -by the attendants into the receiving box C and when sufficiently full motion is given to the worm o5 which revolves the shaft c4 and brings the receiving-box up into the position shown in dotted lines in Fig. 4,

`or further if desired, until it will dump the tobacco on the table. When in this position the tobacco is easily taken therefrom by the attendant or attendants and placed upon the table B. From thence it is passed into the `cylinder through .the aperture a', and the cylinder at the same time is revolved. The

steam is admitted through the pipe E to contact with the tobacco, the effect of which is to soften the tobacco and open its pores and prepare it to receive its casing. The screw anges a3 impel the tobacco forward until it passes into the funnel-shaped end A where 1t 1's received upon the pins a2 which lift and agitare the tobacco as they revolve. The cock t3 is opened and the casing material contained in the tank l is ejected therefrom by the pressure of air through the spraying device t4 which is received by the tobacco while 1t 1s agitated and thoroughly distributed throughout.

It will be seen from this arrangement that the steaming and casing of the tobacco are separate and distinct; that the steaming of the tobacco begins at one end ofthe cylinder and by the time the tobacco has reached the other end it has become sufliciently soft and moist and when in that condition there are devices which separate and agitate it located at that end and in position to receive the casing from its tank. That end of the cylinder is ared or funnel-shaped, and this accomplishes two purposes, it receives the casing material allowing it to run oit and thus keep the rest of the cylinder clean and free from gummin g, it separates the tobacco by making 1t occupy a larger space, and being provided with the agitating devicesl insures that the casing will be evenlydistributed.

What I claim, and desire to secure by Letters Patent, is` l l. In a tobacco preparing and casing apparatus the combination with a revolving cylinder provided with means for impelling the tobacco therethrough and means for applylng steam to the tobacco during its passage, of a funnel-shaped end to said cylinder opposite to the entrance end for the tobacco, provided with separating and agitating devices,

and means for applying the casing material thereto while it is so separated and agitated.

2. In a tobacco preparing apparatus the combination with a revolving cylinder having an open end for receivingthe tobacco and means for impelling the tobacco therethrough of a table B,located in front of the open end of the cylinder, a hinged box wherein the tobacco is placed and arranged, means for hoisting said box and holding it in position to enable the operator to take the tobacco therefrom and prepare it to enter the cylinder.

3. In a tobacco preparing and casing apparatus, the combination with a portable tank for holding the casing material, of a stationary tank, and connections between them through which the casing is forced from the portable to the stationary tank means for supplying compressed air to the portable tank and thereby forcing the casingm to the stationary tank, and means for applying compressed air to the stationary tank to thereby spray the casing therefrom upon the tobacco.

4. In a tobacco preparing and casing apparatus, the combination with a portable tank F. provided with the pipe f4 extending to near the bottom of said tank, of the compressed air pipe H, and the stationary tank I, means for connecting and disconnecting the pipe II- with the tank F and with the pipe f4, means for connecting and disconnecting the tank I with the pipe H and thereby force the casing material from tank F to tank I and forcing it out of tankIto be sprayed upon the tobacco, substantially as described.

Signed at Baltimore, in the State of Maryland, this 24th day of October, A. D. 1893.

CHARLES L. MARBURG.
